Drop in M4 rail

[cop car]

I'm looking at drop in quad rails. Best option I've seen so far is Midwest.

Currently have KAC. While it's acceptable I'm looking for something a bit more solid. Before anyone asks, free float is 100% out of the question. Has to be drop in. I know most people run free float, but seeing if anyone has drop in input.

Midwest makes great stuff, they are definitely under rated. Im surprised you dont like the KAC, mine is rock solid.

Midwest is a great rail. I personally before a little lighter weight and would probably just go with something like the magpul MOE with some rail sections for light/grip

I ran a Troy drop in for awhile on an M4. Very nice rail, drop in installation, then tighten 4 screws on the back of the rail by the delta ring.
At the time it was $120, may be cheaper these days.

I have a drop in free float that I really like. VLTOR CASV. They are cheap and discontinued but solid as a rock. Two problems though; they raise the rail making optics a bit tough to mount & the rear sight notch limits you to a small footprint rear sight.

Troy or Daniel defense. The knights is what we used in the army and then we started using other things. But the knights were always loose on the bottom with a grip.
The top is tightened down against the barrel but with a screw lever system.

i didn't mention Midwest because I have never used their drop in rails. I have used their free float rails and they are
good however I do not like how you have to install them flush with the top receiver rail by tightening or loosening the barrel nut. If you've installed one you know what I mean lol. I Think it's alittle skill and a lot of luck

Kac is my go to now. I have a vltor casv as well, kick ass rail, but yes due to the rriser you need to be careful with the optic and riser to use irons. Just need an SAS/canadian version of the RAS that locks in top and bottom, have one on my lightweight M4

VLTOR is out. That weird ass top rail is a no go. I see that Troy and Daniel Defense both use screws. I'm sure that makes the quite a bit more solid. Anyone with a Midwest have any rattle or movement at all? The KAC moves around quite a bit, main reason why im
Looking for something else.

I have 2x KAC M4 RAS rails and there is zero wobble in both of them. Might be an issue with the barrel nut since all barrel nuts are not the same. I ran into a wonky barrel nut on my first AR(Stag) before I really paid attention to the quality in parts. They also make a RAS II Free Float rail:RAS II SHOT SHOW SPECIAL (2004) BLACK

The DD Omega rails are also rock solid and gives you a free float capability:Daniel Defense Omega Rail Carbine Free Float

Both of these require ZERO modification to the rifle.

I'm a fan of the Knights RAS(having deployed with it several times), but also have a VTAC Alpha that I realz luv! But, the MRP's get the most air time out odpf the safe, and I don't have a choice in that.

ETA:My RAS's have all been rock solid, but it's been a few years since I muzzle bumped a *****?

Daniel Defense omega is free float and works great. I have one on my duty rifle and never had the first problem.

A friend of mine has the Midwest drop in rail on his AR. He seems to like it really well. I've shot with his rifle and it seems to be a very solid piece. It almost made me think about getting one.
